Testing a Single-Line
Network Interface
Plug the telephone’s modular cord into the network
interface and listen for a dial tone.
• If a dial tone is present, the trouble is in the control
unit or the wiring.
• If no dial tone is present, have the local telephone
company check the line and the network interface.
Testing a Two-Line
Network Interface
with an Adapter
Plug the telephone’s modular cord into the network
interface and listen for a dial tone.
Testing a 66-Type
Block
• If a dial tone is present the trouble is in the control
unit or the wiring.
• If no dial tone is present, replace the adapter. If there
is still no dial tone, have the local telephone company
check the line and the network interface.
Use a telephone that has clip leads and test each outside
line for a dial tone. Make sure to remove the bridging
clip
from the block to isolate the outside line from the
MERLIN
II
system.
• If a dial tone is present on some lines and not on
others, check the wiring for damage or broken
connections.
• If a dial tone is present on all lines, check the wiring to
the control unit.
• If no dial tones are present, have the local telephone
company check the lines and the network interface.
